IMPROVEMENT IN OIL-CANS.

Specification forming part of Letters PatentNo. 185,626. dated December26, 1876; application filed April 1, 1876.

To all whom it may concern:

Be it known that we, WM. H. CLARK and WM. J. ULARK, of Salem. in thecounty of Oolnmbiana and State of Ohio, have invented certain new anduseful Improvements in Oil Oans or Tanks; and we do hereby declare thatthe following is a full and complete description of the same, referencebeing bad to the accompanying drawings, making part of thisspecification, in which Figure 1 is a side view of the can. Fig. 2 is avertical section. Fig. 3 is a plan view of the inside. Fig. 4 is a viewof the pump detaehed from the can. Fig. 5 is a vertical section of thebody of the can. Figs. 6 and 7 are detached sections.

Like letters refer to like parts in the several views.

This invention is a safety can or tank for holding oil for immediateuse, and which may also be used for measuring and transporting the samein bulk. A detailed description of the invention is as follows:

In the drawings, A represents the body of the can, the holding capacityof which may be more or less. The upper edge of the can is beveled orslightly flaring, as will be seen at a, in Fig. 2, to which a detachablecover or top, B, is fitted in an oil-tight manner,

as followsz In the under side of the margin of the cover is an annulargroove, b, Fig. 7, formed by a flange, b. Said figure represents asection of the cover, showing the groove. In said annular groove isfitted a packing, c, Fig. 2, which, when the cover is put on the can, ispressed between the annular shoulder C and the back of the groove, inwhich the packing lies. On screwing down the cover, the beveled orflaring edge a of the can causes the packing to wedge between said edgeand annular groove 12, into which it is pressed, thereby making anoil-tight connection of the cover with the rim of the can, the outeredge of which is embraced and supported by the annular shoulder O,forming, as it were, a hoop around the edge of the can, as will be seenin Fig. 2. The screwing down of the cover alluded to is effected by thescrews E passing through the holes d, Fig. 3, and into the lugs F, Fig.2, secured to the inside of the can. The cover, as will be seen in saidFig. 2, is

depressed in the center, and the surface thereof is scored with radialgrooves c, Fig. 3, deepening as they approach the center, the purpose ofwhich will hereinafter be shown. To the top of the cover is secured atruncated hood, G, covering about one-halfof the cover. The top of thehood is partially covered by a horizontal rim, H, the inner edge ofwhich is struck up, forming a standing co1lar,f, Fig. 2. To the insideof the hood is fitted a revolving door, I, the top of which is truncatedand partially covered by a horizontal rim, J, the inner edge of which isstruck up, forming a standing collar, K, similar to the rim and collarof the hood, and inside of which the rim and collar of the revolvingdoor are closely, but loosely, fitted, as will be seen in Fig. 2. Insaid Fig. 2 it will be observed that the edge of the collar K is turnedover upon the edge of the collarf, and upon which the revolving door ispartiallysupported, while being opened and shut. Said collar K, in itsconnection with the collar 1, forms the axis of rotation of therevolving door.

The opening in the center of the top or cover B is lined with a bush, h,Fig. 2, in which is fitted a thimble. L, secured to the pump, M, andwhereby said pump is steadied in position in the body of the can, asshown in said Fig. 2. The upper end of the pump terminates in areceiver, N, made either wholly or in part of glass, and secured theretoby a collar, 0, Fig. 4, provided with a projecting rim, 1;. Said collarfits closely in the collar K of the revolving door, and the rim tprojects over both collars K and f, as will be seen in Fig. 2. Thebottom of the collar 0 is depressed, forming a chamber, P, Figs. 1 and4, through which the pump passes. The bottom of said chamber is madeoil-tight in its connection with the pump by means ofa nut, m, screwedon the pump, and forced against the bottom of the chamber, between whichand the nut is interposed a gasket, n, for forming the joint. Q is astop-cock opening into the chamber P, and R is a ventilatingtube toconduct air from the receiver and tank reciprocally, and for returningoil back into the can from the receiver when said receiver is filled toa certain height.

The pump referred to is or may be an ordinary lifting one, of which M,alluded to, is the stock; A, the rod; B. the valve attached thereto, andO the stationary valve. Said pump is operated from the outside by aknob, D. Immediately below the cap E of the glass receiver N areopenings in the side of the pump, as will be seen at a, in Fig. 2,through which the oil flows from the pump into the receiver.

The practical use of the oil-can is as follows: Oil is drawn from thecan by means of the pump, which it discharges through the holes a,referred to, into the receiver until the latter is full. The vent takesaway surplus, which flows back into the can, thereby insuringcorrectness in measuring. A scale of measure for smaller quantities ismarked on the glass, by which the amount required is drawn therefrom, bythe cock Q, into vessels placed thereunder upon the cover B. Thedrippings and waste that may occur fall upon the cover, and run down inthe grooves e, through the holes 0, Fig. 4, made in the thimble L, alsothrough the holes in bush h of the cover, thence back into the can; saidholes being so arranged in the bush and thimble as to be injuxtaposition, but which may be closed by turning the thimble in thebush to prevent oil from spilling therefrom. in the event the can istipped for moving it, 860.

The can, when not in use for drawing oil therefrom, can be closed by thedoor, thereby securing the contents of the can from fire or otheraccidents. The cover of the can being perfectly tight by means of thepacking c, and the connection of the pump made tight by the gasket andnut, renders the oil safe from leakage, and the escape of gas therefrom.

By the use of the glass receiver, provided with a scale of measurement,measuring-vessels may be dispensed with.

In the event the body of the can only is needed, and that for thetransportation of oil, it can be used for that purpose by detaching thecover B, hood, &c., leaving simply the body of the can, as will be seenin Fig. 5. In place of the cover B is used a wooden head, G, Fig. 6, puton the can, as will be seen in Fig. 5. In said Fig. 5 it will beobserved that in the periphery of the head is cut a groove, in which isplaced a packing, at, similar to the packing 0, whereby the cover B ismade tight to the can. Said head is made fast to the can by screws 6,screwed into the lugs F in the same way as the coverB is secured to thecan.

The can in this condition is used for shipping oil instead of usingbarrels for that purpose.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In combination with the hood G, having a shoulder, H, and collar f,the revolving door I, connected therewith by a collar, K, forming aswivel connection of the two parts, substantially as described, and forthe purpose set forth.

2. In combination with the pump M, can A, and receiver N, theventilating-tube R, at one side of the pump-body, and faucet Q, for thepurpose specified.
